You can't oversimplify the stock market and say, "it's all a pump & dump". How do stocks grow and appreciate in value over time, if it's all a pump & dump? Yes, there a spikes and drops with news and earnings, it happens with all stocks. That's because there is increased buying pressure, eventually levels get overbought and there is consolidation. Day traders & swing traders will cause volatility in stocks- this is normal.People who are in stocks short-term will sell the news as well- is this what you meant? If you really believe that it's simply all a 'pump&dump' then you need to get more experience outside of the OTC markets.
